I assume that you didn't have my problem with wrong CPU frequency

I mean other systems (even not Linux-based) that may

False. From chrony.txt:

4.2.27 makestep

Normally chronyd will cause the system to gradually correct any time
offset, by slowing

Have you filed a bug for the problem which frequency scaling causes for
you (system time going out of whack)?
Have you tried alternative workarounds

As workaround now I can use in F16 kernel from F15.
But when F15 will be EOL no more kernel updates will
be available and using old kernels forever is not good idea.
Is there any chance that

Here's what I use. I hope it can help you.
- Install kernel-tools package
- Start/enable cpupower.se

What negative effects does frequency scaling have for you when using
governor performance?

Frequency scaling have negative effects for me
so I need to have it disabled in BIOS.
I think that this is not BIOS option broken
but broken kernel with built-in cpufreq modules.
If hardware supports disabling frequency scaling
then should be possibility to do this.
BIOS have such possibility, Fed

Hi,
The purpose of this bug was to provide native systemd script for cpuspeed in
Fedora 16
https://bugzilla.redhat.com/show_bug.cgi?id=713572
But instead of adding systemd script which should load cpufreq modules other
solution was provided - cpufreq modules was compiled as built-in in Fedora 16
